A disconnect assembly configured to disconnect a parachute of an aerial delivery apparatus from a payload includes a detector device, a disconnect device, and a transmit cable. The detector device is configured to detect that the aerial delivery apparatus has landed, the disconnect device is configured to provide a releasable connection between the parachute and the payload, and the transmit cable is configured to transmit a mechanical trigger force from the detector device to the disconnect device. When the detector device detects that the aerial delivery apparatus has landed, the transmit cable transmits a mechanical trigger force from the detector device to the disconnect device and the disconnect device releases the connection between the parachute and the payload.

A pressure activated release system and method are disclosed for deployment of surface, aerial and subsea payloads. The system and method include a payload release switch that is activated, without human intervention, by a pressure differential. The system and method also includes a payload release mechanism having an unreleased configuration at pressures below a specified pressure. The release mechanism has a released configuration at pressures above the specified pressure. The switch causes the release mechanism to move from the unreleased configuration to the released configuration.

Cable laying devices for use with aircraft that are airborne are provided, which use a cable spool to deliver cable along a landscape. These devices incorporate a braking means that is actuated by cable tension, a means for cutting the cable which is controlled remotely and/or a motorized winding mechanism.

In an embodiment, a parachute deployment system includes a parachute coupled to a release via a first load path. The first path includes crown lines. The release is adapted to attach the parachute to a rocket via the crown lines, and disengage the parachute from the rocket if a load shifts from the first path to a second path. The system also includes a line constrainer between the release and the parachute. The crown lines pass through the line constrainer, and the line constrainer is adapted to restrict an extent to which the crown lines are able to extend away from a longitudinal axis. An example release includes a back plate configured to couple a tow line to crown lines and a soft pin. The pin is adapted to separate from the back plate in response to tensioning of the release line, causing the parachute to disengage.

An automatic parachute release device is a quick release coupler that becomes disengaged after an externally applied tension load is removed. The parachute release device has a parachute connection fastener, a camlock mechanism, a retention mechanism and a catch pin. The camlock mechanism is a mechanical controller that transitions the retention mechanism between a set configuration and a release configuration. While in the set configuration, the retention device is clamped around the catch pin. While in the release configuration, the retention mechanism disengages the catch pin. Thus, the retentive capabilities of the retention mechanism are governed by the configuration of the camlock mechanism. The retention mechanism remains in the set configuration until the load is removed. At which point, the retention mechanism slides into a dedicated slot of the camlock mechanism and becomes disengaged.

An unmanned aerial vehicle includes multiple rotor arms; a rotor disposed at an end of each of the multiple rotor arms; and an adjustment component configured to enable a first rotor arm to move relative to a second rotor arm.

A device for disconnection by a mechanical action includes at least one mechanical connection part, in particular a buckle held closed by spring action, linked to at least one trigger via at least one connecting member, and a release lever configured to be triggered by application of a force according to a predefined opening direction. The disconnect device also includes at least one guide for the connecting member configured to redirect an effort applied on the trigger, when opening is required, towards the mechanical connection part linked to the connecting member, according to the predefined opening direction.
